RestorFile Ransomware

Posted: November 30, 2020

RestorFile Ransomware Description

The RestorFile Ransomware is a file-locking Trojan or a threat that can block users' personal and work files by encryption or other methods. As part of AES-Matrix Ransomware's family, its encryption routine is probably secure, and victims will need backups for restoring files, typically. Proper security habits also can limit infection opportunities, and most anti-malware programs for Windows should readily delete the RestorFile Ransomware.

Another Campaign's Worth of Surface Area for a File-Eating Matrix

The AES-Matrix Ransomware's threat actor is resorting to leaving off letters in e-mail addresses for the latest Trojan campaign, possibly, due to difficulties avoiding already-in-use names. The RestorFile Ransomware is livelier than most variants of its family, with at least four installer versions circulating with different, random titles. Whether its campaign is reaping the rewards from more victims than usual remains uncertain.

The RestorFile Ransomware operates like other AES-Matrix Ransomware releases, from the Matrix-NOBAD Ransomware and the Matrix-THDA Ransomware up to the BNFD Ransomware and the JB88 Ransomware. It uses AES-128 and RSA-1024 encryption for locking most files on the victims' Windows systems, such as documents, pictures, databases or archives. Separating itself from most other file-locker Trojans, the RestorFile Ransomware is most likely to target enterprise entities and business-related environments, including entire networks or servers.

The RestorFile Ransomware also makes a by-now-typical addition to these files' extensions and creates a ransom note in the AES-Matrix Ransomware family's favored format of RTF. Here, malware analysts find some trivial differences in wording and formatting that make the RestorFile Ransomware's warning message slightly altered from old attacks. However, the overall formula remains demanding a ransom and recommending negotiations over several e-mails, with an additional ID for the victim's identification.

The RestorFile Ransomware also continues to assert a better price for a fast response from victims, facilitating payments before a comprehensive exploration of all recovery possibilities.

Restoring Files without a Trojan's Typo

With installer names like 'file000_z9lq4k8t' or 'bnpykqzd,' users have little chance of identifying this Trojan before it establishes system persistence and continues with blocking most files of any worth on the PC. The AES-Matrix Ransomware family is characterized by manually-guided attacks, which require attackers, first, gaining a foothold through other means. Malware experts connect most cases of corporate network or server breaches back to e-mail tactics, such as fake document attachments delivering backdoor-capable threats or takeovers of accounts with weak passwords. However, other infection vectors remain possible.

Whether as part of a business PC setup or at home, all users should have backups of any ransom-worthy content, including documents, pictures, audio, databases, archives, video and other digital media. Only a minority of file-locker Trojans use encryption that's sufficiently-fragile that a third-party could break it. Additionally, like most of the more significant families of this type, the RestorFile Ransomware deletes the Restore Points backups as a matter of habit.

After an infection, users can withhold any ransom money and recover from backups as appropriate. The usual PC security services should remove the RestorFile Ransomware, but users should treat login credentials for their current accounts as likely-compromised.

The most efficient way of stopping business-minded Trojans like the RestorFile Ransomware is making their models unprofitable. Every legal business that uses a server with a risky password or fails to maintain backups helps the illegal file-locker Trojan industry.
